Unmanned aerial vehicle movement via environmental airflow

ABSTRACT

An arena includes a porous surface through which an airflow is output, thereby providing lift for an unmanned aerial vehicle (UAV) to push the UAV away from the porous surface. The airflow may also provide thrust to push the UAV in a direction that is parallel to the porous surface. The UAV may include one or more propellers that can provide lift, thrust, or both to the UAV. The airflow may be modified over a duration of time to modify lift or thrust to the UAV. The airflow may be modified based on regions of the arena to modify lift or thrust in different regions of the arena. The arena may include a scoreboard to display a score that may be modified as a result of actions undertaken by the UAV. Two or more UAVs may be used to play a game via the arena.

Unmanned aerial vehicles (UAVs), sometimes referred to as “drones,” are aerial vehicles that are either autonomous, remote-controlled by a user with a control transmitter, or some combination thereof. UAVs can sometimes include cameras that record images or videos of the physical world as seen by the field of view of the camera.

Augmented reality refers to a view of a physical, real-world environment whose elements are augmented or supplemented by computer-generated sensory input. For example, augmented reality may include the view of the physical environment with text or images adding to or replacing elements of the view of the physical environment. Augmented reality may also insert or replace sounds with computer-generated sounds.

Virtual reality refers to technologies that generate, typically via compute software, a virtual world environment whose elements have little or no relationship to any physical, real-world environment. A virtual reality experience is typically intended to replace, rather than augment or supplement, an experience of any physical reality.

DETAILED DESCRIPTION

An arena includes a porous surface through which an airflow is output, thereby providing lift for an unmanned aerial vehicle (UAV) to push the UAV away from the porous surface. The airflow may also provide thrust to push the UAV in a direction that is parallel to the porous surface. The UAV may include one or more propellers that can provide lift, thrust, or both to the UAV. The airflow may be modified over a duration of time to modify lift or thrust to the UAV. The airflow may be modified based on regions of the arena to modify lift or thrust in different regions of the arena. The arena may include a scoreboard to display a score that may be modified as a result of actions undertaken by the UAV. Two or more UAVs may be used to play a game via the arena.

FIG. 1A illustrates an exploded view of an arena system with multiple fans, two unmanned aerial vehicles (UAVs), and two goals.

The arena system of FIG. 1A is illustrated as a raised table, but may be lowered to the ground in another embodiment. The arena system includes an airflow generating layer 120 and a surface layer 115.

The arena system of FIG. 1A also includes one or more arena devices 180, which are computing devices 1100. References hereafter to a single arena device 180 should be understood to apply to multiple arena devices 180 as well. The arena device 180 may aid in controlling operations of the arena hardware via hardware of the arena device 180, software stored in one or more memory units of the arena device 180 and executed via one or more processors of the arena device 180, or some combination thereof. While the arena device 180 of FIG. 1A is illustrated as connected to the arena of FIG. 1A through a wire, it may alternately be connected to the arena of FIG. 1A wirelessly via Bluetooth, Wi-Fi, cellular signals, infrared, or some combination thereof. Likewise, the arena device 180 of FIG. 1A may communicate with the left unmanned aerial vehicle (UAV) 110L and the right unmanned aerial vehicle (UAV) 110R wirelessly via Bluetooth, Wi-Fi, cellular signals, infrared, or some combination thereof.

The airflow generating layer 120 of FIG. 1A includes multiple fans 125 that generate an airflow, where at least a component of the airflow is directed vertically toward the surface layer 115 as illustrated in FIG. 10B. These fans 125 may be controlled by the arena device 180, by a controller transmitter 800, or some combination thereof.

The airflow generated by the fans 125 at the airflow generating layer 120 is then output through pores in a surface 110 of the surface layer 115. That is, the surface 110 is a porous surface. The surface 110 is illustrated with visible holes, but in other cases, the surface 110 may be made at least partially of a naturally porous fabric or other material whose pores are not easily visible.

A left unmanned aerial vehicle (UAV) 110L and a right unmanned aerial vehicle (UAV) 110R are also illustrated in FIG. 1A. While the UAVs 100 are illustrated as traditional UAVs 100 propelled fully by motorized propellers, the UAVs need not have any propellers at all. Instead, the UAVs 100 of FIG. 1A may be lifted above the surface 110 via lift 1010 provided by the airflow generated by the fans 125 of the airflow generating layer 120, much like an air hockey puck as illustrated further in FIG. 10A. The UAVs 100 may also include motorized propellers to supplement or replace the lift 1010 supplied by the airflow. Horizontal thrust 1020 may also be provided by the airflow, by the motorized propellers of the UAV 100, or some combination thereof, as illustrated further in FIG. 10A.

The arena system of FIG. 1A also includes a left goal 105L and a right goal 105R. These may be used in the process of operating a game involving the left unmanned aerial vehicle (UAV) 110L and the right unmanned aerial vehicle (UAV) 110R.

FIG. 1B illustrates an exploded view of an arena system with a single fan, two unmanned aerial vehicles (UAVs), and two goals.

The arena system of FIG. 1B is identical to the arena system of FIG. 1A except that the airflow generating layer 120 of FIG. 1B only includes a single fan 125. The airflow generated by the single fan 125 may be channeled by additional components of the airflow generating layer 120 and/or of the surface layer 115, such as tubes, that allow the airflow generated by the single fan 125 to be output relatively evenly out of each of the pores of the surface 110.

A large arena system may also include a few fans 125 similar to the one in FIG. 1B, with the airflow generated by each fan 125 channeled to be output relatively evenly out of each of the pores of a region of the surface 110.

FIG. 1C illustrates an arena system with two unmanned aerial vehicles (UAVs), two goals, a ball, and a scoreboard.

The arena system of FIG. 1C is similar to the arena systems of FIG. 1A and FIG. 1B, though all of the parts described in those figures are put together rather than illustrated in an exploded view. The arena system of FIG. 1C also adds a ball 140 and a scoreboard 145. The scoreboard 145 is illustrated as displaying a score of three (3) to five (5). The scoreboard 145 may be used in the playing of a game involving the arena system of FIG. 1C, the ball 140, the left unmanned aerial vehicle (UAV) 110L, the right unmanned aerial vehicle (UAV) 110R, the left goal 105L, and the right goal 105R.

The game illustrated in FIG. 1C may be a game similar to soccer, hockey, or air hockey. For example, the left unmanned aerial vehicle (UAV) 110L may score a point by pushing the ball 140 into the right goal 105R, and the right unmanned aerial vehicle (UAV) 110R may score a point by pushing the ball 140 into the left goal 105L.

Different implementations of such a game may use baskets or hoops instead of goals 105, much like basketball, and the UAVs 100 may have a motorized or spring-loaded claw or arm or catapult to help launch the ball 140 into such a basket or hoop. Different implementations of such a game may use endzones instead of goals 105, much like American football. Different implementations of such a game may use more than one ball 140. Different implementations of such a game may use pucks rather than balls 140. Different implementations of such a game may use more UAVs 100, such as to have two teams of UAVs, with multiple UAVs 100 on each team, to make the game more similar to team sports such as soccer, basketball, lacrosse, American football, rugby, hockey, water polo, bocce ball, curling, or some combination thereof.

Sensors may be placed in the goals 105, along the surface 110, or elsewhere in the arena system to detect when the ball 140 has entered the goal. The sensors may notify the scoreboard 145 to increment the score corresponding to the appropriate UAV 100. The sensors may include pressure sensors, motion sensors, or cameras capable of recognizing the ball 140 via image recognition processes involving the arena device 180. The camera of either UAV 100 may also detect a successful goal and notify the scoreboard 145 of the goal. The sensors may include radar sensors, sonar sensors, lidar sensors, or some combination thereof. The sensors may include laser rangefinders. The ball 140 may include a wireless emitter, and the sensors may thus be receivers able to recognize when the ball is in the goal by the signals received by the ball. The ball itself 140 may include any such sensors as well, and may notify the scoreboard 145 of a successful goal itself. The sensors may also be located away from the surface 110, such as overhead or off to the side, by being mounted on a wall or ceiling or on another UAV 100 that serves as a “referee.” The sensors may also include location sensors, such as GPS receivers, which may be particularly useful if the arena is large, or triangulation-based location sensors that triangulate a location from wireless signals emitted at different known locations. The sensors may include gyroscopes and/or accelerometers onboard each of the UAVs 100.

The wireless emitter may be a sound emitter, such as a speaker, that may emit audible sound at human hearing frequencies or inaudible sound at frequencies higher or lower than human hearing frequencies. The wireless emitter may be a different type of wireless emitter, such as a Bluetooth, wifi, cellular, light, or radio emitter.

A UAV 100 may “see” the ball 140 even when it is not in the field of view of the camera of the UAV 100 by using onboard receivers corresponding to the wireless emitter in the ball 140 to sense emissions 230 output by the ball 140 and use those to detect the location of the ball 140, for example by gauging when the signal gets stronger as the UAV 100 and/or ball 140 moves.

FIG. 1D illustrates the arena system of FIG. 1D with two disc-shaped unmanned aerial vehicles (UAVs). In particular, the left UAV 100L and the right UAV 100R are both disc-shaped. The motorized propellers of these disc-shaped UAVs 100 are primarily for thrust 1020 rather than lift 1010; they instead rely on the airflow generated by the airflow generating layer 120 and output through the pores in the surface 110 for lift 1010. These disc-shaped unmanned aerial vehicles (UAVs) are further illustrated in FIG. 7B.

FIG. 2 illustrates an arena system with two unmanned aerial vehicles (UAVs), two base regions, a flag, and a scoreboard.

The arena system of FIG. 2 is arranged for a “capture the flag” style of game. The arena system of FIG. 2 includes a left base region 210L and a right base region 210R. The arena system of FIG. 2 also includes flag 220, which may include a flag emitter 225 that may be any type of wireless emitter discussed with respect to FIG. 1C. This may be used to detect when the flag 220 is in a particular base region 210, and to send a signal to the scoreboard 145 to increment the score associated with the appropriate UAV 100.

For example, the left UAV 100L may gain a point by getting the flag 220 to the left base region 210L and/or by keeping the flag 220 there for a predetermined period of time. The right UAV 100R may gain a point by getting the flag 220 to the right base region 210R and/or by keeping the flag 220 there for a predetermined period of time. UAVs 100 could score points by stealing the flag 220 from each other as well.

The UAVs 100 may “see” the flag 220 even when it is not in the field of view of their camera by using onboard receivers corresponding to the wireless emitter in the flag emitter 225 to sense the emissions 230 and use those to detect the location of the flag 220, for example by gauging when the signal gets stronger as the UAV 100 and/or flag 220 moves.

The UAVs 100 may move the flag by grabbing it with a motorized or spring-loaded claw, or grab the flag 220 magnetically, or may move the flag 220 by pushing it via the body of the UAV 100 or pulling it via a hook or claw or loop or lasso mounted on the UAV 100.

The base regions 210 may be marked on the surface 110, for example by being printed on the surface 110, by being taped onto the surface 110 by a human user, by being projected onto the surface 110 via a projector (not shown), or by being displayed on the surface 110 in an embodiment wherein the surface 110 includes a display system 1170. The base regions 210 may also include wireless emitters so that the UAVs 100 know where they are even the base regions 210 are not in the field of view of the camera of the UAV 100.

Sensors on the flag 220, along the surface 110, onboard either UAV 100, or some combination thereof may be used to detect when the flag 220 has entered or exited a base region 210. The sensors may be any of the types of sensors discussed in relation to FIG. 1C. Each base region 210 may have sensors. The sensors may also be located away from the surface 110, such as overhead or off to the side, by being mounted on a wall or ceiling or on another UAV 100 that serves as a “referee.”

FIG. 3 illustrates an arena system with two unmanned aerial vehicles (UAVs) equipped with laser emitters and light detectors, a ceasefire region, and a scoreboard.

The arena system of FIG. 3 is arranged for a “laser tag” style game. The UAVs 100 of FIG. 3 include laser emitters and light sensors. The laser emitters are configured to emit a laser 310. The light sensor onboard each UAV 100 is configured to detect when the UAV 100 is “hit” or “tagged” by a laser 310. When a UAV 100 detects that it is hit, it may send an update to the scoreboard 145 to detract a point from its own score and/or to increase the score of the UAV 100 that hit it. In situations where multiple UAVs 100 are playing laser tag, the arena device 180 may receive signals from all of the UAVs 100 whenever each UAVs 100 fires a laser 310 and/or is hit by a laser 310, and may determine which UAV 100 fires a particular laser 310 that hit a particular target UAV 100 based on laser firing time and laser hit time as reported by the UAVs 100, as well by locations and/or directional headings as reported the UAVs 100.

The arena system of FIG. 3 includes a ceasefire region 320, whose boundaries may be identified as described regarding the base regions 210 of FIG. 2. A UAV 100 in the ceasefire region 320 may have its laser emitter disabled and/or may have its light sensor disabled.

FIG. 4 illustrates an arena system with multiple regional airflow effects.

The arena system of FIG. 4 illustrates three (3) regional airflow effects along 410 different regions of the surface 110. These airflow effects are identified in FIG. 4 as regional airflow effect 410A, regional airflow effect 410B, and regional airflow effect 410C, respectively. The different regional airflow effects 410 are illustrated as affecting cylindrical volumes of different radii, but they may affect differently shaped volumes as well, such as spherical volumes, ovoid volumes, or some combination of spherical, ovoid, and cylindrical volumes. The regional airflow effects 410 may include, for example, regions with stronger-than-usual lift, weaker-than-usual lift, no lift, maximum lift, a “wind” that supplies thrust in a particular direction, a tornado-style vortex, or some combination thereof.

Regional airflow effects 410 may be controlled by the arena device 180, by the control transmitter 800, or some combination thereof. The regional airflow effects 410 and may more specifically be produced when the airflow generating layer 120 includes multiple fans 125, and in particular, when different fans 125 are coaxed to produce different strengths and/or directions of airflow compared to the remainder of the fans 125 or just to neighboring fans 125. For example, one fan 125 can be spun faster than its neighboring fans 125, producing increased lift 1010 over the region of the surface 110 affected by the faster fan 125 compared to the regions of the surface 110 affected by the slower neighboring fans 125.

Each UAV 100 may be made aware of locations with regional airflow effects 410 by receiving signals identifying locations of regional airflow effects 410 from the arena device 180, or by receiving emissions 230 from wireless emitters located along the surface 110 that emit at locations where regional airflow effects 410 are present. Alternately, a projector may project an image or video on to the surface 110 indicating a regional airflow effect 410; this may then be recognized by the UAV 100 via image recognition.

FIG. 5A illustrates a field of view of an unmanned aerial vehicle (UAV) during a game involving a ball.

The UAV field of view 505 of FIG. 5A illustrates a view from the camera 705 of the UAV 100. A ball 140 and a perimeter of the surface 110 is visible in the UAV field of view 505. The camera 705 may capture the UAV field of view 505 as an image or video, and may transmit this as a camera feed to the display 900, where the user may view the UAV field of view 505. The camera feed may be transmitted in real-time or with a delay for processing or otherwise.

The camera feed may be transmitted directly from the UAV 100 to the display 900, or indirectly through the arena device 180 or control transmitter 800. The camera feed may be modified before it is displayed at the display 900 to portray an augmented reality view as illustrated in FIG. 5B.

The modifications to the camera view may be made by a computing device 1100 onboard the UAV 100, by a computing device 1100 onboard the display 900, by a computing device 1100 onboard the control transmitter 800, by the arena device 180, by a separate computing device 1100 communicatively coupled to any of these devices, or some combination thereof. The modifications to the camera view may involve various computer vision techniques implemented via hardware, software, or some combination thereof. These computer vision techniques may include edge detection, tracking, pattern recognition, character recognition, 3D segmentation, 3D modeling, counting, quantification, machine learning, face detection, logo detection, optical character recognition, barcode scanning, quick response (QR) code scanning, or some combination thereof.

The camera feed may include data from multiple cameras to provide depth perception and identify distances between the UAV 100 and objects in the UAV field of view 505. The camera feed may include data from a distance measurement system, such as a laser rangefinder, a radar device, a sonar device, or a lidar device, to provide depth perception and identify distances between the UAV 100 and objects in the UAV field of view 505. Image recognition and tracking may be based on one or more shapes, one or more colors, one or more brightness levels, one or more contrast levels, a relative size, an absolute size, one or more facial features, one or more logos, one or more barcodes, one or more QR codes, one or more reference points, or some combination thereof.

The display field of view 510 of FIG. 5B also illustrates a score overlay 530 identifying the score on the scoreboard 145 as well as labels for objects not in the UAV field of view 505, including the enemy's goal 105, the enemy UAV 100, and the user's goal 105.

The UAV field of view 605 of FIG. 6A also illustrates a second “enemy” UAV 100 that is “hit” or “tagged” by the laser 310. The UAV field of view 605 of FIG. 6A also illustrates a perimeter of the surface 110 and markings on the surface 110 indicating a ceasefire region 320.

The display field of view 610 illustrates the ceasefire region 320 as a three-dimension volume by extending it upwards from the markings on the surface 100 of the UAV field of view 605. The display field of view 610 illustrates labels identifying the enemy UAV 100, the ceasefire region, and the hit by the laser 310.

FIG. 7A shows unmanned aerial vehicle (UAV) 100 according to a first embodiment. UAV 100 can have one or more motors 750 configured to rotate attached propellers 755 in order to control the position of UAV 100 in the air. UAV 100 can be configured as a fixed wing vehicle (e.g., airplane), a rotary vehicle (e.g., a helicopter or multirotor), or a blend of the two. For the purpose of FIG. 7, axes 775 can assist in the description of certain features. If UAV 100 is oriented parallel to the ground, the Z axis can be the axis perpendicular to the ground, the X axis can generally be the axis that passes through the bow and stern of UAV 100, and the Y axis can be the axis that pass through the port and starboard sides of UAV 100. Axes 775 are merely provided for convenience of the description herein.

In some embodiments, UAV 100 has main body 710 with one or more arms 740. The proximal end of arm 740 can attach to main body 710 while the distal end of arm 740 can secure motor 750. Arms 740 can be secured to main body 710 in an “X” configuration, an “H” configuration, a “T” configuration, a “Y” configuration, or any other configuration as appropriate. The number of motors 750 can vary, for example there can be three motors 750 (e.g., a “tricopter”), four motors 750 (e.g., a “quadcopter”), eight motors (e.g., an “octocopter”), etc.

In some embodiments, each motor 755 rotates (i.e., the drive shaft of motor 755 spins) about parallel axes. For example, the thrust provided by all propellers 755 can be in the Z direction. Alternatively, a motor 755 can rotate about an axis that is perpendicular (or any angle that is not parallel) to the axis of rotation of another motor 755. For example, two motors 755 can be oriented to provide thrust in the Z direction (e.g., to be used in takeoff and landing) while two motors 755 can be oriented to provide thrust in the X direction (e.g., for normal flight). In some embodiments, UAV 100 can dynamically adjust the orientation of one or more of its motors 750 for vectored thrust.

In some embodiments, the rotation of motors 750 can be configured to create or minimize gyroscopic forces. For example, if there are an even number of motors 750, then half of the motors can be configured to rotate counter-clockwise while the other half can be configured to rotate clockwise. Alternating the placement of clockwise and counter-clockwise motors can increase stability and enable UAV 100 to rotate about the z-axis by providing more power to one set of motors 750 (e.g., those that rotate clockwise) while providing less power to the remaining motors (e.g., those that rotate counter-clockwise).

Motors 750 can be any combination of electric motors, internal combustion engines, turbines, rockets, etc. In some embodiments, a single motor 750 can drive multiple thrust components (e.g., propellers 755) on different parts of UAV 100 using chains, cables, gear assemblies, hydraulics, tubing (e.g., to guide an exhaust stream used for thrust), etc. to transfer the power.

In some embodiments, motor 750 is a brushless motor and can be connected to electronic speed controller X45. Electronic speed controller 745 can determine the orientation of magnets attached to a drive shaft within motor 750 and, based on the orientation, power electromagnets within motor 750. For example, electronic speed controller 745 can have three wires connected to motor 750, and electronic speed controller 745 can provide three phases of power to the electromagnets to spin the drive shaft in motor 750. Electronic speed controller 745 can determine the orientation of the drive shaft based on back-end on the wires or by directly sensing to position of the drive shaft.

Transceiver 765 can receive control signals from a control unit (e.g., a handheld control transmitter, a server, etc.). Transceiver 765 can receive the control signals directly from the control unit or through a network (e.g., a satellite, cellular, mesh, etc.). The control signals can be encrypted. In some embodiments, the control signals include multiple channels of data (e.g., “pitch,” “yaw,” “roll,” “throttle,” and auxiliary channels). The channels can be encoded using pulse-width-modulation or can be digital signals. In some embodiments, the control signals are received over TC/IP or similar networking stack.

In some embodiments, transceiver 765 can also transmit data to a control unit. Transceiver 765 can communicate with the control unit using lasers, light, ultrasonic, infra-red, Bluetooth, 802.11x, or similar communication methods, including a combination of methods. Transceiver can communicate with multiple control units at a time.

Position sensor 735 can include an inertial measurement unit for determining the acceleration and/or the angular rate of UAV 100, a GPS receiver for determining the geolocation and altitude of UAV 100, a magnetometer for determining the surrounding magnetic fields of UAV 100 (for informing the heading and orientation of UAV 100), a barometer for determining the altitude of UAV 100, etc. Position sensor 735 can include a land-speed sensor, an air-speed sensor, a celestial navigation sensor, etc.

UAV 100 can have one or more environmental awareness sensors. These sensors can use sonar, LiDAR, stereoscopic imaging, computer vision, etc. to detect obstacles and determine the nearby environment. For example, a collision avoidance system can use environmental awareness sensors to determine how far away an obstacle is and, if necessary, change course.

Position sensor 735 and environmental awareness sensors can all be one unit or a collection of units. In some embodiments, some features of position sensor 735 and/or the environmental awareness sensors are embedded within flight controller 730.

In some embodiments, an environmental awareness system can take inputs from position sensors 735, environmental awareness sensors, databases (e.g., a predefined mapping of a region) to determine the location of UAV 100, obstacles, and pathways. In some embodiments, this environmental awareness system is located entirely on UAV 100, alternatively, some data processing can be performed external to UAV 100.

Camera 705 can include an image sensor (e.g., a CCD sensor, a CMOS sensor, etc.), a lens system, a processor, etc. The lens system can include multiple movable lenses that can be adjusted to manipulate the focal length and/or field of view (i.e., zoom) of the lens system. In some embodiments, camera 705 is part of a camera system which includes multiple cameras 705. For example, two cameras 705 can be used for stereoscopic imaging (e.g., for first person video, augmented reality, etc.). Another example includes one camera 705 that is optimized for detecting hue and saturation information and a second camera 705 that is optimized for detecting intensity information. In some embodiments, camera 705 optimized for low latency is used for control systems while a camera 705 optimized for quality is used for recording a video (e.g., a cinematic video). Camera 705 can be a visual light camera, an infrared camera, a depth camera, etc.

A gimbal and dampeners can help stabilize camera 705 and remove erratic rotations and translations of UAV 100. For example, a three-axis gimbal can have three stepper motors that are positioned based on a gyroscope reading in order to prevent erratic spinning and/or keep camera 705 level with the ground. Alternatively, image stabilization can be performed digitally using a combination of motion flow vectors from image processing and data from inertial sensors such as accelerometers and gyros.

Video processor 725 can process a video signal from camera 705. For example video process 725 can enhance the image of the video signal, down-sample or up-sample the resolution of the video signal, add audio (captured by a microphone) to the video signal, overlay information (e.g., flight data from flight controller 730 and/or position sensor), convert the signal between forms or formats, etc.

Video transmitter 720 can receive a video signal from video processor 725 and transmit it using an attached antenna. The antenna can be a cloverleaf antenna or a linear antenna. In some embodiments, video transmitter 720 uses a different frequency or band than transceiver 765. In some embodiments, video transmitter 720 and transceiver 765 are part of a single transceiver.

Battery 770 can supply power to the components of UAV 100. A battery elimination circuit can convert the voltage from battery 770 to a desired voltage (e.g., convert 12v from battery 770 to 5v for flight controller 730). A battery elimination circuit can also filter the power in order to minimize noise in the power lines (e.g., to prevent interference in transceiver 765 and transceiver 720). Electronic speed controller 745 can contain a battery elimination circuit. For example, battery 770 can supply 12 volts to electronic speed controller 745 which can then provide 5 volts to flight controller 730. In some embodiments, a power distribution board can allow each electronic speed controller (and other devices) to connect directly to the battery.

In some embodiments, battery 770 is a multi-cell (e.g., 2S, 3S, 4S, etc.) lithium polymer battery. Battery 770 can also be a lithium-ion, lead-acid, nickel-cadmium, or alkaline battery. Other battery types and variants can be used as known in the art. Additional or alternative to battery 770, other energy sources can be used. For example, UAV 100 can use solar panels, wireless or inductive power transfer, a tethered power cable (e.g., from a ground station or another UAV 100), etc. In some embodiments, the other energy source can be utilized to charge battery 770 while in flight or on the ground.

Battery 770 can be securely mounted to main body 710. Alternatively, battery 770 can have a release mechanism. In some embodiments, battery 770 can be automatically replaced. For example, UAV 100 can land on a docking station and the docking station can automatically remove a discharged battery 770 and insert a charged battery 770. In some embodiments, UAV 100 can pass through docking station and replace battery 770 without stopping.

Battery 770 can include a temperature sensor for overload prevention. For example, when charging, the rate of charge can be thermally limited (the rate will decrease if the temperature exceeds a certain threshold). Similarly, the power delivery at electronic speed controllers 745 can be thermally limited—providing less power when the temperature exceeds a certain threshold. Battery 770 can include a charging and voltage protection circuit to safely charge battery 770 and prevent its voltage from going above or below a certain range.

UAV 100 can include a location transponder. For example, in a racing environment, race officials can track UAV 100 using location transponder. The actual location (e.g., X, Y, and Z) can be tracked using triangulation of the transponder. In some embodiments, gates or sensors in a track can determine if the location transponder has passed by or through the sensor or gate.

Flight controller 730 can communicate with electronic speed controller 745, battery 770, transceiver 765, video processor 725, position sensor 735, and/or any other component of UAV 100. In some embodiments, flight controller 730 can receive various inputs (including historical data) and calculate current flight characteristics. Flight characteristics can include an actual or predicted position, orientation, velocity, angular momentum, acceleration, battery capacity, temperature, etc. of UAV 100. Flight controller 730 can then take the control signals from transceiver 765 and calculate target flight characteristics. For example, target flight characteristics might include “rotate x degrees” or “go to this GPS location”. Flight controller 730 can calculate response characteristics of UAV 100. Response characteristics can include how electronic speed controller 745, motor 750, propeller 755, etc. respond, or are expected to respond, to control signals from flight controller 730. Response characteristics can include an expectation for how UAV 100 as a system will respond to control signals from flight controller 730. For example, response characteristics can include a determination that one motor 750 is slightly weaker than other motors.

After calculating current flight characteristics, target flight characteristics, and response characteristics flight controller 730 can calculate optimized control signals to achieve the target flight characteristics. Various control systems can be implemented during these calculations. For example a proportional-integral-derivative (PID) can be used. In some embodiments, an open-loop control system (i.e., one that ignores current flight characteristics) can be used. In some embodiments, some of the functions of flight controller 730 are performed by a system external to UAV 100. For example, current flight characteristics can be sent to a server that returns the optimized control signals. Flight controller 730 can send the optimized control signals to electronic speed controllers 745 to control UAV 100.

In some embodiments, UAV 100 has various outputs that are not part of the flight control system. For example, UAV 100 can have a loudspeaker for communicating with people or other UAVs 100. Similarly, UAV 100 can have a flashlight or laser. The laser can be used to “tag” another UAV 100.

FIG. 7B shows unmanned aerial vehicle (UAV) 100 according to a second embodiment. UAV 100 likewise includes one or more motors 750 configured to rotate attached propellers 755 in order to control the position of UAV 100 in the air. The motorized propellers of the UAV 100 of FIG. 7B, however, are oriented more horizontally and are used primarily or exclusively to provide thrust 1020 rather than lift 1010. Lift 1010 is instead provided by airflow generated by the airflow generating layer 120 and output via the pores of the surface 110. The body of the UAV 100 of FIG. 7B is more disc-shaped so that a larger percentage of the surface area of the UAV 100 encounters the airflow, maximizing lift 1010. The motorized propellers of the UAV 100 may be reversibly driven as well for greater movement control.

Though not all of the UAV components illustrated in FIG. 7A are illustrated in FIG. 7B, it should be understood that the UAV 100 of FIG. 7B may include any of the components that are illustrated in FIG. 7A or discussed elsewhere herein. Some of those may be hidden within the housing/body of the UAV 100 of FIG. 7B, or some may be placed over the body/housing in a manner more similar to the UAV 100 of FIG. 7A. For example, the UAV 100 of FIG. 7B is illustrated with a top housing protecting its components—however, the an alternate embodiment (not pictured), the UAV 100 of FIG. 7B may have a complete disc only at its bottom, and at least some of the components of the UAV 100 of FIG. 7B may be more exposed from above and/or from the sides (e.g., in a manner similar to FIG. 7A) in order to make the UAV 100 lighter.

While this disc-shaped embodiment of the UAV 100 is only illustrated in FIG. 1D and FIG. 7B, it should be understood that it may be used anywhere else that the UAV 100 of FIG. 7A is illustrated, such as in the context of FIG. 2, FIG. 3, FIG. 4, FIG. 6A, FIG. 6B, and FIG. 10A.

While the disc-shaped embodiment of the UAV 100 is illustrated with four (4) motorized propellers, it may only have one motorized propeller, particularly if the motorized propeller can be reversibly driven. On the other hand, the UAV 100 may have more than four (4) motorized propellers as well, for additional maneuverability. In yet another embodiment (not pictured), the UAV 100 may have no motorized propellers, but may have both its lift 1010 and its thrust 1020 provided entirely by the airflow generated by the airflow generating layer 120 and output through the pores in the surface 110.

FIG. 8 shows control transmitter 800 according to some embodiments. Control transmitter 800 can send control signals to transceiver 765. Control transmitter can have auxiliary switches 810, joysticks 815 and 820, and antenna 805. Joystick 815 can be configured to send elevator and aileron control signals while joystick 820 can be configured to send throttle and rudder control signals (this is termed a mode 2 configuration). Alternatively, joystick 815 can be configured to send throttle and aileron control signals while joystick 820 can be configured to send elevator and rudder control signals (this is termed a mode 1 configuration). Auxiliary switches 810 can be configured to set options on control transmitter 800 or UAV 100. In some embodiments, control transmitter 800 receives information from a transceiver on UAV 100. For example, it can receive some current flight characteristics from UAV 100.

The control transmitter 800 may control the airflow of the arena system as described herein, in addition to controlling the motorized propellers of the UAV 100. While the control transmitter 800 is illustrated as wireless and separate from the arena system, it should be understood that it may be wired to the arena system, such as by appearing as controls embedded in the raised arena “table” illustrated in FIGS. 1A, 1B, 1C, 2, 3 and 4.

FIG. 9 shows display 900 according to some embodiments. Display 900 can include battery 905 or another power source, display screen 910, and receiver 915. Display 900 can receive a video stream from transmitter 720 from UAV 100. Display 900 can be a head-mounted unit as depicted in FIG. 9. Display 900 can be a monitor such that multiple viewers can view a single screen. In some embodiments, display screen 910 includes two screens, one for each eye; these screens can have separate signals for stereoscopic viewing. In some embodiments, receiver 915 is mounted on display 900 (as shown in FIG. 9), alternatively, receiver 915 can be a separate unit that is connected using a wire to display 900. In some embodiments, display 900 is mounted on control transmitter 800.

FIG. 10A illustrates a side view of an unmanned aerial vehicle (UAV) experiencing lift and thrust.

In particular, the UAV 100 is experiencing lift 1010 that is perpendicular to the surface 110 and away from the surface 110. This direction may also be describes as parallel and opposite to the direction of gravity. The lift 1010 may be provided by the airflow output through the pores in the surface 110, or by the motorized propellers of the UAV 100 itself, or some combination thereof. While the direction of lift 1010 is perpendicular to the surface 110 and away from the surface 110, this does not mean that the airflow output through the pores of the surface 110 necessarily moves exactly perpendicular to the surface 110—rather, only a component of the airflow's force need provide the lift 1010 as illustrated in FIG. 10B (e.g., the perpendicular component 1060 of FIG. 10B). Similarly, this does not mean that any force supplied by the motorized propellers of the UAV 100 is necessarily exactly perpendicular to the surface 110—rather, only a component of the force supplied by the motorized propellers need provide the lift 1010 as illustrated in FIG. 10B (e.g., the perpendicular component 1060 of FIG. 10B).

The UAV 100 is also experiencing thrust 1020 in a direction that is parallel to the surface 110. This direction may also be describes as perpendicular to the direction of gravity. The thrust 1020 may be provided by the airflow output through the pores in the surface 110, or by the motorized propellers of the UAV 100 itself, or some combination thereof. While the direction of thrust 1020 is parallel to the surface 110, this does not mean that the airflow output through the pores of the surface 110 necessarily moves exactly parallel to the surface 110—rather, only a component of the airflow's force need provide the thrust 1020 as illustrated in FIG. 10B (e.g., the parallel component 1070 of FIG. 10B). Similarly, this does not mean that any force supplied by the motorized propellers of the UAV 100 is necessarily exactly parallel to the surface 110—rather, only a component of the force supplied by the motorized propellers need provide the thrust 1020 as illustrated in FIG. 10B (e.g., the parallel component 1070 of FIG. 10B).

FIG. 10B illustrates a force diagram of an airflow output by the arena.

The airflow force 1040 is illustrated at an acute angle from the surface 110. The force diagram of FIG. 10B illustrates that the airflow force 1040 includes two components, namely a “perpendicular” or “vertical” component 1060 and a “parallel” or “horizontal” component 1070.

The “perpendicular” or “vertical” component 1060 is perpendicular to the surface 110 and typically along the same vector direction as the gravitational force. The perpendicular component 1060 may provide lift 1010 to the UAV 100 as illustrated in FIG. 10A.

The “parallel” or “horizontal” component 1070 is parallel to the surface 110 and typically along the vector direction that is perpendicular to the gravitational force. The parallel component 1070 may provide thrust 1020 to the UAV 100 as illustrated in FIG. 10A.

The airflow force 1040 may be at an angle as illustrated in FIG. 10B for a number of reasons. In some embodiments of the arena, the fan(s) 125 may themselves be capable of being tilted, and such tilting may be actuated by a motor over a duration of time, for example in response to a signal from the control transmitter 800. The arena may also channel the airflow from fan(s) 125 in ways that causes the airflow to be output at an angle, such as via angled tubes. In situations with multiple fans 12 as in FIG. 1A, the combined airflow of multiple fans 125 may be output at an angle due to disparity between magnitude of airflow force output by different fans in a region, for example by supplying more power to a first fan 125 than to a second fan 125 right next to the first.

While airflow force 1040 is illustrated at an acute angle from the surface 110, though it should be understood that any angle is possible, including a right angle or an obtuse angle.

While the force 1040 is labeled as an “airflow” force, it should be understood that this also applies to any force generated by the motorized propellers of the UAV 100. That is, a force generated by the motorized propellers of the UAV 100 may also be broken down into component forces whose vector directions are the same as the perpendicular component 1060 and the parallel component 1070 of FIG. 10B.

FIG. 11 illustrates an exemplary computing system 1100 that may be used to implement an embodiment of the present invention. For example, any of the computer systems or computerized devices herein, such as the UAV 100, the control transmitter 800, the display 900, or the arena device 180 may, in at least some cases, include at least one computing system 1100.

The system software for implementing embodiments of the present invention may be stored on such a portable medium and input to the computer system 1100 via the portable storage device 1140.

Input devices 1160 provide a portion of a user interface. Input devices 1160 may include an alpha-numeric keypad, such as a keyboard, for inputting alpha-numeric and other information, or a pointing device, such as a mouse, a trackball, stylus, or cursor direction keys.

The display system 1170 may include multiple-touch touchscreen input capabilities, such as capacitive touch detection, resistive touch detection, surface acoustic wave touch detection, or infrared touch detection. Such touchscreen input capabilities may or may not allow for variable pressure or force detection.
